[Control measures for circuit board dust]
During the processing of a PCB manufacturer, the cutting machine dust is small, dense and difficult to collect. Floating in the workshop for a long time, it is easy to be directly inhaled by the staff. Because the dust is exposed to the air for a long time, a large number of viruses or bacteria are attached to each dust particle, which will cause a high incidence of respiratory diseases.
Therefore, PCB company decided to efficiently control the circuit board dust in the factory, so it asked Dongsheng Environmental Protection Company to help your factory solve this problem. Faced with the situation of your company and the characteristics of the dust from the circuit board cutting machine, Dongsheng Environmental Protection The engineer designed a set of pulse bag filter for it.
When the pulse bag filter of this kind of PCB dust treatment equipment is working, when the dust-containing waste gas enters the ash hopper of each unit through the lower part of the middle box through the air inlet, large particles of dust fall directly into the ash hopper due to inertial collision and natural settlement. The remaining dust enters the filter area of the middle box with the airflow, and the dust accumulates on the outer surface of the filter bag. The filtered clean air passes through the filter bag and is discharged through the upper box and exhaust pipe to achieve the purpose of dust removal.
The filtered dust is collected by the ash hopper at the bottom of the dust collector and processed regularly.
After the installation and operation of the system is completed, the air quality is far higher than the local environmental protection standards, and no secondary pollution occurs during the dust removal process, which reduces the operating cost of the equipment. And pass the environmental protection acceptance.
[Detailed introduction to the advantages of the circuit board]
1. It can be bent, wound, and folded freely, can be arranged according to the space layout requirements, and can be moved and stretched in three-dimensional space, so as to achieve the integration of component assembly and wire connection, and high flexibility.
2. In the assembly and connection of components, the conductor cross-section of the FPC soft board is thinner and flat compared with the use of conductive cables, which reduces the size of the conductors and can be formed along the casing, making the structure of the equipment more compact and reasonable, not only can be reduced The volume of electronic products has also reduced a lot of weight to meet the needs of the development of electronic products in the direction of size, miniaturization, and high reliability.
3. Use the FPC soft board to install the connection, which eliminates the error when wiring with wires and cables. As long as the processing drawings are proofread and passed, all the winding circuits produced later will be the same. There will be no wrong connection when installing the connecting line, and the consistency of the installation and connection is guaranteed.
4. When the FPC soft board is installed and connected, because it can be wired on the three planes of X, Y, and Z, the switching interconnection is reduced, the reliability of the entire system is increased, and the inspection of the fault is provided convenient.
5. According to the requirements of use, when designing the FPC soft board, the parameters such as capacitance, inductance, characteristic impedance, delay and attenuation can be controlled, and it can be designed to have the characteristics of a transmission line, and the electrical parameters are highly controllable.
